WARNING: Do not allow the unit to run for more than two minutes without
the gun trigger being pulled. This could cause overheating and damage to
the pump. When the temperature inside the pump rises too high, the thermal
relief valve will open and release a spray of water from the pump to lower the
internal temperature. The valve will then close.
Thermal Relief Valve (L, fig. 5): When the temperature inside the
pump rises too high, this valve will open and release a gush of water
in an effort to lower the temperature inside the pump. The valve will
then close.
Detergent Injection System: Mixes cleaners or cleaning solvents with the water
to improve cleaning effectiveness.
Water Supply: All pressure washers must have a source of water. The minimum
requirements for a water supply are 20 PSI and 5 Gallons Per Minute. If your water
source is a well, the garden hose length can only be 30 ft. (9 m) max.
WARNING: To reduce the possibility of contamination always protect
against backflow when connected to a potable water system.
pRESSURE WASHER OpERATING FEATURES
pRESSURE ADJUSTMENTS
The pressure setting is preset at the factory to achieve op ti mum pres sure and
cleaning. If you need to lower the pres sure, it can be accomplished by these meth-
ods.
1. Back away from the sur face to be cleaned. The further away you are, the
less the pressure will be on the surface to be cleaned.
2. Change to the 40˚ nozzle. This nozzle delivers a less powerful stream of water
and a wider spray pattern. Refer to how To Use Spray Wand.
NOTICE: DO NOT attempt to increase pump pressure. A higher pressure setting
than the factory set pressure may damage pump.
HOW TO USE SpRAY WAND
There are five spray pattern settings located on the 5n1 Multi-tip Nozzle. To select a
spray pattern, rotate the spray selector to the desired setting. Refer to the following
chart to choose the correct nozzle for the job to be performed.
DANGER: Risk of fluid injection. Do not direct discharge stream toward
persons, unprotected skin, eyes or any pets or animals. Serious injury will
occur.
WARNING: Flying objects could cause risk of serious injury. Do not attempt
to change nozzles while pressure washer is running. Turn engine off before
changing nozzles.

*NOTICE: The high pressure spray from your pressure washer is capable of
causing damage to surfaces such as wood, glass, automobile paint, auto striping
and trim, and delicate objects such as flowers and shrubs. Before spraying, check
the item to be cleaned to assure yourself that it is strong enough to resist damage
from the force of the spray.
HOW TO AppLY CHEMICALS/CLEANING SOLvENTS (FIG. 6)
Applying chemicals or cleaning solvents is a low pressure operation. NOTE: Use
only soaps and chemicals designed for pressure washer use. Do not use bleach.
To Apply Chemicals:
1. Ensure detergent siphon hose (F, Figure 6) is attached
tobarbed fitting location near high pressure hose
connection of pump as shown.
2. Place other end of detergent siphon hose with filter on
it into container holding chemical/cleaning solution.
NOTE: For every 7 gallons of water pumped 1 gallon
of chemical/cleaning solution will be used.
3. Select the SOAP setting on the 5n1 Multi-tip Nozzle,
see how To Use Spray Wand paragraph in this section.
4. After use of chemicals, place detergent siphon hose into container of clean
water and draw clean water through chemical injection system to rinse system
thoroughly. If chemicals remain in the pump, it could be damaged. Pumps
damaged due to chemical residue will not be covered under warranty.
NOTE: Chemicals and soaps will not siphon if the soap nozzle is not selected on
the 5n1 Multi-tip Nozzle.
STARTING (FIG. 7–10)
WARNING: To reduce the risk of injury, read the pressure washer instruction
manual and the engine instruction manual before starting pressure washer.
DANGER: Risk of fluid injection and laceration. When using the high
pressure setting, DO NOT allow the high pressure spray to come in contact
with unprotected skin, eyes, or with any pets or animals. Serious injury will
occur.
